Question

A network engineer configures an edge router to send SNMP notifications to an NMS across a WAN link that occasionally experiences packet loss. The engineer notices that certain critical link-down notifications never appear in the NMS console, even though the router logs show the events. The current configuration uses 'snmp-server host 10.1.1.10 version 2c NETMON'. Which change will improve the reliability of notification delivery to the NMS?

Accepted Answer

Configure 'snmp-server host 10.1.1.10 informs version 2c NETMON' so the router expects an acknowledgment and retransmits

Answer

Increase the SNMP trap queue length with 'snmp-server queue-length 100' to buffer more traps

Answer

Change to SNMPv3 with 'priv' security level to encrypt the notifications end to end

Answer

Add 'snmp-server trap-source Loopback0' so notifications use a stable source address
